DCI Paul Fotheringham, of Kent Police, told the inquest: “A post mortem was carried out by a forensic pathologist and the initial results were inconclusive.

"Forensic samples were obtained and the results concluded the recent use of heroin and that the levels identified were likely to have played a role in her death.”

The grand chamber at Gravesend Old Town Hall heard Peaches’ husband, musician Tom Cohen, took the couple’s two young boys, 11-month-old Phaedra and two year old Astala, to stay with his parents in south-east London on Thursday April 3.

Mr Fotheringham said: “This is a normal occurrence which enables Peaches and Thomas to complete work in their respective careers.”

The model and journalist spoke to her husband, family and friends on the phone over the following days before Tom’s dad, Keith, took Phaedra back home at around 5pm on Sunday.

Mr Fotheringham said Peaches “seemed her normal self” and had been planning a family outing for the following weekend.

”To all her friends and family... there was no cause for any concern,” the officer said.

The last known contact she had was a phone call to a friend at 7.45pm the same night.

On Monday morning, Tom tried without success to call his wife.

Worried, he and his mum, Sue, went to the couple’s home in the leafy village of Wrotham and found Peaches dead.

Mr Fotheringham said: “Thomas entered the property and went upstairs, thinking she was sleeping.

"He found her in a spare bedroom. It was obvious to him she was deceased.

"She was located on the edge of the bed with one leg hanging down to the floor and the other leg tucked underneath her.

"She was slumped forward across the bed.”

Phaedra was found elsewhere in the £2m house, the inquest heard.

Kent Police started an investigation but the death was “unexplained with no third party” involvement.

Mr Hatch adjourned the inquest to allow police the time to carry out further investigations.

A full hearing will take place on July 23.No-one from the Geldof family was at the inquest.
